-- Fix buffer overflow in autoload path construction for oversized class/path names #3932
-- Fix Swoole integration parsing the POST body regardless of `DD_TRACE_HTTP_POST_DATA_PARAM_ALLOWED` #3931

-- Fix `php.compilation.total_time_ms` reporting values 1000x too large (microseconds labeled as milliseconds) #3915 (thank you @dortort!)
-- Fix memory corruption of INIs in ZTS builds #3898
-- Fix data race in curl header assignment (non-atomic write to `_Atomic` field) #3945

-- Fix multi-request failures caused by incorrect rinit ordering after tracer/ext split #3946
+- Fix `SpanStack::$active` unset corruption #3962
+- Fix sandbox not saving/restoring `jit_trace_num` #3964
+- Fix `SpanStack` state corruption when tracing objects with deep clone operations #3976
+- Fix `request_exec` being issued between requests #3939
+- Fix Azure Functions instance name resolution DataDog/libdatadog#2077

 ### Internal
-- Split the tracer code into a separate `tracer/` directory within the extension #3912
-- Improve crashtracker reliability: socket-based thread collection, incomplete stack handling, and `language:native` tag DataDog/libdatadog#2080, DataDog/libdatadog#2079, DataDog/libdatadog#2083
+- Fix crashtracker metadata: correctly distinguish JIT disabled vs opcache disabled, and correct system INI classification #3965
+- Use libdatadog's CSS trace filter implementation, aligning filtering behavior with the agent #3986, DataDog/libdatadog#1985
+- Add configurable sidecar connection retry interval #3977, DataDog/libdatadog#2106
+- Emit `_dd.svc_src` span tag per Service Override Source Attribution RFC #3948

 ## Profiling
+### Added
+- Add trampoline for frameless functions (FLF) to correctly capture timings on aarch64 and x86_64 #3595
+- Add experimental heap-live profiling for memory leak detection, enabled via `DD_PROFILING_EXPERIMENTAL_HEAP_LIVE_ENABLED` (requires allocation profiling to be active) #3623
+
 ### Fixed
-- Fix macOS release builds for the profiler #3923
+- Fix profiler crashes and hangs: stderr fd leak (`O_CLOEXEC` missing) causing child processes to hang, NULL file dereference in timeline error observer on PHP 8.0, and async signal delivery to helper threads causing a segfault on ZTS builds #3364
+- Fix macOS release builds for the profiler #3987
 
 ### Internal
-- Support PHP DEBUG builds for the profiler, enabling ASAN testing in CI #3908
+- Replace `lazy_static` with `std::sync::LazyLock` and optimize `Sapi`/`RefCellExt` #3990
+- Simplify profiler name/version string constants to compile-time values #3998
 
 ## AppSec

+- Enable Rust helper by default for all PHP versions (can be disabled with `DD_APPSEC_HELPER_RUST_REDIRECTION=false`) #3991
 
-### Fixed
-- Fix out-of-bounds iteration in PHP <8.1 backtrace `HashTable` loop in the AppSec backtrace collection path #3933
